Description:

This error code indicates that the Corner Post Display Unit (PDU) is not receiving the required messages from the Cab Switch Module (CSM). This can be due to communication failures, wiring issues, or faults within the CSM or PDU.

Reaction:

There is no immediate reaction from the control unit; however, the absence of these messages can lead to incomplete or missing switch-related information on the PDU, affecting the operator’s ability to monitor and control various cab functions.

Recommendations:

• Inspect Communication Lines:
  • Check the wiring and connectors between the PDU and CSM for any signs of damage, loose connections, or interference.
• Verify CSM Operation:
  • Ensure that the CSM is functioning properly and transmitting the required messages.
• Update Software:
  • Update the software of both the PDU and CSM to the latest versions to ensure compatibility and proper communication protocols.
• Reset the System:
  • Perform a system reset to reestablish communication between the PDU and CSM.
• Consult Technical Support:
  • If the communication issue persists, contact technical support for further diagnostics and solutions.

Note:

Maintaining clean and secure connections between the PDU and CSM, along with regular software updates, is crucial for reliable communication and cab switch function management.
